Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2022.

Research

• A study on the biomarker composition of gut contents in Ediacaran macrofossils is published by Bobrovskiy et al.

(2023).
• Evidence that yunnanozoan branchial arches consisted of cellular cartilage with an extracellular matrix dominated by microfibrils (a feature hitherto considered specific to vertebrates) is presented by Tian et al. (2022), who interpret this finding as supporting the conclusion that yunnanozoans were stem vertebrates; their conclusions are subsequently contested by He et al. (2023) and Zhang & Pratt (2023).

History of life in general

• Eckford-Soper et al. (2022) argue that the size distribution of preserved eukaryotic microfossils dating to 1.7 billion years ago and onward is most compatible with an active eukaryote ecosystem complete with phototrophy, osmotrophy, phagotrophy and mixotrophy.

(2022) report fossils of the cystoporate bryozoan Fistulipora przhidolensis and unidentified trepostomes intergrown with auloporid tabulate corals and putative hydrozoans from the Silurian (Přídolí) Ohesaare Formation (Estonia), and interpret the studied bryozoans and cnidarians as forming mutually beneficial associations, representing the oldest cases of such associations reported to date.

• A study on patterns of latitudinal diversity gradients of marine invertebrate fossils during climatic changes from the Carboniferous icehouse to the Triassic greenhouse climates is published by Zhang, Shen & Erwin (2022), who interpret their findings as indicating that peaks of the latitudinal diversity gradients may be shaped by multiple factors rather than alternating icehouse and greenhouse climates.
• A study on the modifications to cranial anatomy in the early evolution of tetrapods is published by Rawson et al. (2022), who interpret their findings as indicating that reduction in the number of skull bones across the origin of tetrapods was associated with increased density (remaining bones acquired more connections), but also with skulls with fewer bones becoming more integrated and less modular across the fish-tetrapod transition, while no such change to skull construction was found between the first stem tetrapods and crown tetrapods from later in the Paleozoic.

• A study on an outcrop containing hundreds of Induan tetrapod fossils in the southern Karoo Basin of South Africa, including clusters of up to eight closely spaced Lystrosaurus skeletons (two of which display an envelope which is likely a permineralised mummified skin), is published by Smith, Botha & Viglietti (2022), who interpret this finding as evidence for episodes of drought-induced mass death, indicative of intensification of continental aridity ~252 million years ago by greenhouse gasses from the Siberian traps.
• A study on the ecological state of the Early Triassic benthic fauna from the Hiraiso Formation (Japan), comparing it with coeval assemblages from around the world, is published by Foster et al.

(2022) present evidence of a trophic cascade from the Upper Triassic Xujiahe Formation (Sichuan, China), describing insect eggs placed between the upper and lower cuticles of the ginkgophyte Baiera multipartita, and interpreting punctures on the eggshell surfaces as indicating that the studied eggs were damaged by a predatory insect.

• A study on the magnitude of ecological change from the Campanian to the Danian, as indicated by fossil record of North American vertebrates, is published by García-Girón et al. (2022), who interpret their findings as indicative of trophic restructuring in the latest Cretaceous dinosaur faunas, with decline of megaherbivores being counterbalanced by stronger influence of medium-sized species on Maastrichtian food webs, but otherwise indicating that dinosaur niches were stable and static, which might have placed dinosaurs at a disadvantage in the event of an abrupt shutdown of the trophic network, while smaller vertebrates, including mammals, consistently increased their impact on food webs, beginning in the latest Cretaceous and continuing in the Paleocene.

• Fernández-Monescillo et al. (2022) document fossil material of the notoungulate species Mesotherium cristatum from the middle Pleistocene deposits in the west Pampean Region of the Córdoba Province (Argentina), representing a new Last Appearance Datum for this species, and interpret this finding as indicating M. cristatum should no longer be considered as the guide taxon of the Ensenadan, and that the temporal boundaries of the biostratigraphic units established for the Pampean Region can only be supported by fossil evidence and not by the temporal boundaries of the chronostratigraphic units as has been used so far.
• A study on the stratigraphy and age for the Trinil site (Java, Indonesia) and its fossils is published by Hilgen et al. (2022), who interpret their findings as challenging the assumption that the Trinil H. K. Fauna – which includes Homo erectus – is a homogeneous biostratigraphic unit.

Other research

• A continuous record of atmospheric CO₂ during the Permian-Triassic transition from the Shangsi section (China) is presente by Shen et al. (2022), who also study changes of marine phytoplankton community structure across this interval, and interpret their findings as indicating that while the first extinction pulse of the Permian–Triassic extinction event in the latest Permian appears to have been associated with intense initial weathering that briefly suppressed the atmospheric CO₂, it was followed by a rapid rise to a prolonged high atmospheric CO₂, and the second extinction pulse in the Early Triassic was sustained by food web collapse driven by the expansion of bacterial production in response to oligotrophic conditions.

• A study on the history and legality of Myanmar amber use in the literature, providing evidence of links between research interest in Myanmar amber and major political, legal and economic changes, and indicating that the vast majority of publications on this amber do not include researchers from Myanmar as co-authors, is published by Dunne et al. (2022).
• Stewens, Raja & Dunne (2022) review the history of fossil removal under colonial rule, and evaluate potential avenues for their return under public international law.

Paleoclimate
